Exp: Molecular Modeling - newman projection: staggered - newman projection: eclipsed - Newman Projection Conformations and their relative energies [draw a graph] - The gauche conformation of butane occurs when the dihedral angle between at the C1-C2 and C3-C4 is 60 degrees. There is sterric strain in the molecule due the proximity of the two methyl groups. Would the sterric strain in this molecule increase OR decrease C1-C2-C3 [and C2-C3-24] bond angle was increased to more than 109.5...

1. A patient has undergone overnight oximetry. Data shows several episodes of O2 desaturation throughout the night. The RTT would expect orders for which of the following kinds of testing: a. V/Q scan b. pulmonary function testing c. polysomnography d. 24-hour Holter monitoring - Answer- Your answer: C Correct answer: C The use of overnight oximetery is often used to detect O2 desaturation during the night that may be associated with central or obstructive sleep apnea. Because data...

After completing the procedure of the laboratory experiment in its entirety, it was concluded that phosphate concentration was in direct proportion to absorbance in each of the three cola samples. The trend line equation, “y = 0.107x + 0.549” summarizes the correlation between absorbance and concentration in phosphate solutions. When applied to this particular experiment, the equation yields a concentration of .61 M for Coke. This was the highest concentration of the three samples, foll...

MMSC407 Final Exam Questions with Correct Answers Describe the characteristics of light as an energy source. - Answer-1. Wavelength - the distance between the crests of two successive waves 2. Amplitude - the height of each wave 3. Frequency - the number of waves which pass an observation point in one second In terms of energy: -High energy = high frequency, short wavelength -Low energy = low frequency, long wavelength Describe the relationship between percent transmittance and abso...
